Nissan has developed the Leaf Dream Drive, a music album simply for the sake of parents having trouble lulling their babies to sleep to the ambiance of a humming engine without the revving emissions, so the parents don’t have to put their baby to sleep by driving.

It was introduced on Monday and referred to the album as “the world’s first zero-emission lullaby.”

Although research revealed that parents believed that it’s the vehicle’s movement that encourages sleep, “in fact, it is the soothing sound frequencies of an internal combustion engine (ICE) that is the biggest contributor to a child falling asleep in the car.”

The soundtrack was created specifically for the model Nissan Leaf due to being powered by an electric powertrain, which doesn’t have the same calming effect as an ICE car in taking babies out for a ride. It contains five tracks lasting three minutes containing the sound frequencies and rhythms of a combustion engine that can be played in a battery-powered vehicle.

The soundtrack is also available on Apple Music, Spotify, SoundCloud, YouTube, and Deezer, so parents can loop the lullaby in the car and keep themselves at ease.
